Well, that depends on how you interpret the question and which name resolution
system you use. If you use the DNS it's quite reasonable to have the same
name refer to all the interfaces on a machine. A reasonable resolver would
then choose the nearest one.

This is a different interpretation of the question. What you're actually
doing here is associating *addresses* with the interfaces, not names. Stated
that way, if you prefer to have symbolic names for those addresses then
obviously you need to have different symbolic names.
What we do is have the canonical name translate to all the addresses, together
with additional interface-specific names. Something like:
myhost IN A 141.241.4.36
IN A 141.241.160.8
myhost-4 IN A 141.241.4.36
myhost-160 IN A 141.241.160.8
and in your reverse zone:
36.4 IN PTR myhost.my.dom.ain.
8.160 IN PTR myhost.my.dom.ain.

Rubbish!
